For those of you who may understand. I am trying to be able to consistently hit low balls that are out of my strike zone. This is the biggest problem I find when I play bad players, versus better ones. The better ones, the ball sits at waist/shoulder height and I can swing as hard as I want. However when I play with people who play with no spin and just get it over, I almost have a hard time using my regular swing. What I do often is frame the ball when swinging hard. Anyways I included a video to show what I meant.

What LeeD said isn't wrong, IMO. Fundamentally those short hop balls are a bit harder to hit.

But I'd also add that I think you can improve your fh form a bit and help the problem you specifically brought up. On your backswing your arm goes way back towards the back fence, essentially straight and pointing at the back fence. That's a whole lota take back. Ernest Gulbis does that, but it's not the general take back that you see. As you swing forward, the racquet head, most or all of the racquet, and often your hand go behind the plane of your body and then must swing all the way out to the front.

And just to be clear about body plane I'm referring to, it's the plane that's formed by your chest and at the time you start your forward swing. So when you start your swing your chest is perpendicular to the net (which is good), therefore so is that plane.

If you can shorten your take back, and keep the racquet in front of the plane of your body, you'll have more control, and probably more power and spin too. The more control part will help with the low, short balls. Here's a great video on the difference between the bigger takebacks (WTA) and a more modern takeback:

Wow ok that was eye opening, thank you so much for the tips and the video. Yes, my grip is SW. I always assumed since I am a thin guy (130lbs) that if I had a large enough backswing I could increase racquet head speed. I often swing as hard as I can since my swing is now developed to not fly to the fences, however on the other hand I just don't hit the ball hard enough to create winners unless I REALLY lean into it and hit it very accurately. I really would like to be 20 pounds heavier with more muscle to take advantage of more power, however I just can't.

I will try the shorter backswing tommorow; I am playing my father in the morning. I will let you know how it goes.

On size, I'm 6' tall and 170 lb. I hit with a guy who is around 5' 9", and 145 lb. He's a 5.0 player and hits the ball like a hammer - especially off his fh. Tons of pace and spin. I've spent the last two years trying to get up to his level. I'm still not there overall, but I have learned to dish out pace and spin on his level (with reasonable consistency) and using the ATP style forehand is the key on the forehand side.

On the ATP style take back: it's probably going to take a bit to get it down - lord knows I'm still working on it. You might want to try it against a wall and video yourself a few times. Shadow swing in a mirror first just really slowly and get the feel. Then go to the wall and do it slowly. Those foam practice balls might be a good investment because it slows everything down. It's weird, but often times more subtle changes to a stroke are harder to incorporate then a total change
